Molten-Salt-Based Thermal Storage for Thermal Power Unit Plant Peaking

Energies
As the integration of renewable energy sources continues to increase, thermal power units are increasingly required to enhance their operational flexibility to accommodate grid fluctuations. However, frequent load variations in conventional thermal power plants result in decreased efficiency, accelerated equipment wear, and high operational costs.

Analysis of Primary Frequency Regulation Ability of Shandong Power Grid Thermal Power Unit

Journal of Physics: Conference Series, 2021
Abstract Shandong Power Grid is about to achieve the development goal of 30% of new energy power generation installed capacity, 30% of foreign power input into Shandong, and 30% of thermal power installed capacity. Neither new energy power generation nor external power has the ability to adjust primary frequency.

Interaction between Molten Al‐Killed Mn–B Steel and Carbon‐Bonded MgO Refractories Based on Recyclates

Advanced Engineering Materials, EarlyView.
High‐temperature interactions between low‐sulfur Al‐killed Mn–B steel and MgO–C refractories (0 and 50 wt% recyclates) are studied via finger immersion tests (1600 °C). Surface‐active elements influence infiltration. MgO/CaS layer forms, along with spinel and calcium silicate.

Dynamic Control Method of Thermal Power Units Compensating for Wind Power Disturbance

IOP Conference Series: Earth and Environmental Science, 2019
Abstract The randomness and volatility of wind power generation are the main reasons restricting the capacity of power grid to absorb wind power. Thermal power units are the main force of power grid frequency modulation. The speed of load adjustment rate determines their response ability to power grid load.
